BTW, regarding the Mishna in Kesuvos I quoted, I read it last night but don’t have the mesechta here now. It said “she enters her husband’s “Reshus” for Nisu’in”, so how is it talking about a ketana?
Because it’s a continuation of the previous Mishna which is clearly talking about a Ketana/Na’arah.
